Abstract��
The impact of vehicle angular and vibrational motion on the star imaging process was researched, and the mathematical model of motion blur corresponding to various flight states was deduced and established then. On this basis, the mechanism of multiple motion blur was discussed. In order to ensure the accuracy and stability of star sensor under high dynamic conditions, a step-by-step restoration was proposed to remove the multiple blur of star image. The simulation results indicate that the star centroiding accuracy caused by vehicle motion is related with specific motion type and parameters, and the restoration method is validated by comparing the attitude estimates before and after the restoration of blurred star image.
